Stateful Contextually-Aware Access Control for ICS

Technical Abstract

Industrial Control Systems (ICS) stay abreast with the Internet revolution by improving their productivity and efficiency through the use of standard networking technology that enables remote access and mobile systems. With trends to improve production by leveraging supply chains to a global scale and outsourcing services for improved efficiency, management and security, care must be taken to ensure that the very services and devices entering the ICS whether remotely or thru a mobile environment do not further introduce or are introduced to security vulnerabilities.

This paper will describe how the use of stateful and contextually-aware access control systems can aide in both the visibility as well as the enforcement of when and how devices can access and control ICS functions.
